Every year, more and more devices are getting eSIM support, which shows the widespread adoption of this technology. Therefore, if you have purchased such a smartphone, you do not necessarily need to buy and install a physical SIM card. All you need to do is choose an operator and tariff, and then activate the SIM. And you can even do it remotely. We tell you what the advantage of the new technology is and how to use data only eSIM.
What is a Data Only eSIM?
An eSIM is a miniature electronic SIM card that is built directly into a smartphone and does not require physical replacement. This innovation fundamentally changes traditional approaches to the use of mobile communications, offering users more flexible and convenient connectivity options.
The eSIM system is usually installed right at the production line in flagship smartphone models. These SIM cards cannot be removed, thrown away or inserted into another phone.
With a virtual SIM card, you can download the best digital tariff, install it on your gadget and connect your mobile network in just a few minutes. Providers offer different tariff options for digital SIM cards. For example, you can buy an eSIM for data only. It is a tariff plan that allows you to use only a package of mobile traffic, without call and SMS services.
The main advantage of eSIM is its ability to support multiple operators simultaneously, allowing the user to easily switch between tariff plans and countries without having to physically swap virtual SIM cards. This is especially useful for international travelers who want to avoid high roaming charges.
Technically, the eSIM functions through profiles that are downloaded and managed remotely. The user can add or remove these profiles through special applications or menus in the device. The profiles are fully digital and can be instantly changed according to the user’s needs.
3 Ways to Make Phone Calls with a Data Only eSIM?
Calls through a virtual SIM card are made in the same way as through a regular SIM card: you select the contacts of the subscriber or enter the number manually, then press the call button. But can you call with eSIM that only works for data. There are three working ways to do this: through special VoIP applications, through social networks and using the main SIM card.
Make Calls Using VoIP Apps
Even with a data-only eSIM, you can still make voice and video calls through popular VoIP apps. These apps allow contact syncing and work well for both domestic and international communication.

Use Data Only eSIM to Call via Social Media
Another convenient way to make calls with an eSIM for data only is to use social media. For example, Facebook, Instagram, WeChat:
| Platform | Call Types | Common Restrictions | Notes |
|---|---|---|---|
| Voice, Video | May limit call quality on poor connections | Requires Facebook Messenger app | |
| Video | Limited to contacts who follow you back | Available via direct messages | |
| Voice, Video | Some features may be limited by region | Requires verification for full access |
Note! Don’t forget to disable Internet roaming on your physical SIM card, so that you don’t have to spend your tariff on roaming during the call.
Use Your Primary SIM card
You can send messages and make calls while traveling through a physical SIM card using its tariff. But in this case you may be charged roaming money. Therefore, it is better to clarify this point early.
Making a call is easy with a regular sim card. But first you need to perform a few actions:
- go to settings;
- enable the physical SIM card;
- allow calls and messages via the main card.
After that, your device will be used for traffic, but when you want to call or text, the phone will switch to the physical card.
